The NFS clients are web servers running Apache. I want to be sure that if my NFS server dies that I don't get odd problems (e.g., the default hard NFS option will cause the process to hang, and I can't kill it). I realize that the hard option is meant to support an NFS environment where a NFS server comes back up, and everything just pops back to normal, but that hasn't been my experience. I am willing to accept that if an NFS server dies that my processes will get errors from the IO operation. I am currently using these options in /etc/fstab: rw,bg,soft bg is essential for us since a server will hang on boot-up if an NFS server is down. It's amazing how if one server is down then chances are a lot of them are. Murphy's Law. What options do you feel the most comfortable with? We are willing to lose a new write to a file if an NFS server dies. It's more important that I can quickly bring the server back up using our backup NFS server for example. I can't do that if my process becomes completely unresponsive. Just asking for general feelings on this issue.
